WLC configuration

Answer: A,B

Question No: 33

A wired packet that is marked for QoS priority CS4 arrives on VLAN-4 at Cisco WLC v7.0, with a destination of a WLAN SSID-4. The Cisco WLC is configured for the wired and wireless QoS level of Silver. The infrastructure routers and switches have incorrect QoS configurations. They have mismarked the CAPWAP outer header to a QoS priority EF.

Which statement is true about how the packet is sent from the AP to the final WMM wireless client?

The AP sends the packet with an 802.11 priority tag of 0 (Best Effort).

The AP sends the packet with an 802.11 priority tag of 3 (Silver).

The AP sends the packet with an 802.11 priority tag of 5 (Gold).

The AP sends the packet with an 802.11 priority tag of 6 (Platinum).
